“…In addition, appropriate electrical driving schemes and resistance capacitance (RC) limitations have to be taken into account to reduce the device parasitic effects on the high frequency response of the device. We note that optical modulation based on free carrier effects in III-V semiconductors has also been investigated previously [26,27]. It was suggested that the device speed for a reversebiased pn junction is only limited by the RC constant.…”

We present a high-speed and highly scalable silicon optical modulator based on the free carrier plasma dispersion effect. The fast refractive index modulation of the device is due to electric-field-induced carrier depletion in a Silicon-on-Insulator waveguide containing a reverse biased pn junction. To achieve high-speed performance, a travelling-wave design is used to allow co-propagation of electrical and optical signals along the waveguide. We demonstrate high-frequency modulator optical response with 3 dB bandwidth of ~20 GHz and data transmission up to 30 Gb/s. Such high-speed data transmission capability will enable silicon modulators to be one of the key building blocks for integrated silicon photonic chips for next generation communication networks as well as future high performance computing applications.

“…Here, the higher light confinement allows for minimizing the interaction (crosstalk) between adjacent components, thus enabling dense on-chip integration of photonic structures. During the past forty years, the vast majority of developments such as optical modulators/switches [27][28][29] or on-chip lasers [30,31], among others, have made use of 3D rectangular WGs.…”

This paper reviews the application of coherent acoustic phonons in the form of surface acoustic waves to control the response of semiconductor optical waveguide devices. We lay special emphasis on devices built upon three-dimensional rectangular waveguides, which offer excellent possibilities for integration due to the stronger confinement of the optical fields. We address the spatial distribution of the acoustic fields, as well as the excitation of surface acoustic waves in piezoelectric materials using interdigital transducers. The mechanisms responsible for the interaction between light and the acoustic modes in the optical waveguides, as well as the influence of waveguide parameters in the performance of the devices, are also discussed. Finally, we review the most important advances on the modulation of semiconductor optical waveguide devices built upon three-dimensional waveguides, and explore several exciting future technological possibilities. These include, among others, the generation of slow light in photonic crystal waveguides to enhance the sound-light interaction in the reviewed devices.
